I'm converting my garage to an ADU (aka mother in-law home) and as part of the project, am connecting to the sewer in our house about 25' away. Not having designed a 1st floor bath on a slab before- I'm wondering if there is a standard for how deep I should be trying to get the sewer line when it hits the garage? I know enough to make sure it's graded at least 1/8"foot for 4" drain, and no more than 1/4" per foot.
Obviously trying to minimize how deep of a trench I need to be digging between buildings. Currently it's dug to just below the bottom of the slab in the garage, but clearly I'll need some more depth to account for plumbing under the toilet and shower drain.
Toilet is going to be right where the trench lands at the garage, and the shower drain is about 15' from the toilet.
Any suggestions off top of head? Or should I get some drawings going to explain better?
Thanks for your input ya'll.
